متن کاملAutomatic Detection and Quantitative DCE-MRI Scoring of Prostate Cancer Aggressiveness
Purpose To develop a robust and clinically applicable automated method for analyzing Dynamic Contrast Enhanced (DCE-) MRI of the prostate as a guide for targeted biopsies and treatments. Materials and methods An unsupervised pattern recognition (PR) method was used to analyze prostate DCE-MRI from 71 sequential radiotherapy patients. Identified regions of interest (ROIs) with increased perfus...
متن کاملCell membrane water exchange effects in prostate DCE-MRI.
Prostate Dynamic-Contrast-Enhanced (DCE) MRI often exhibits fast and extensive global contrast reagent (CR) extravasation - measured by K(trans), a pharmacokinetic parameter proportional to its rate. This implies that the CR concentration [CR] is high in the extracellular, extravascular space (EES) during a large portion of the DCE-MRI study. Since CR is detected indirectly, through water proto...
متن کاملFeasibility of shutter-speed DCE-MRI for improved prostate cancer detection.
The feasibility of shutter-speed model dynamic-contrast-enhanced MRI pharmacokinetic analyses for prostate cancer detection was investigated in a prebiopsy patient cohort. Differences of results from the fast-exchange-regime-allowed (FXR-a) shutter-speed model version and the fast-exchange-limit-constrained (FXL-c) standard model are demonstrated. Although the spatial information is more limite...
متن کاملEvaluation of DCE-MRI postprocessing techniques to assess metastatic bone marrow in patients with prostate cancer.
Dynamic contrast-enhanced magnetic resonance imaging was performed in control patients with normal bone marrow and patients with untreated bone metastases of prostate cancer (PCa). Perfusion data were assessed using region of interest-based and pixel-wise current standard postprocessing techniques (signal intensity pattern, increase in signal intensity, upslope, time to peak, extended Kety mode...
